The list of prime factors of all numbers are

Prime factors of 694 are 2 x 347

Prime factors of 604 are 2 x 2 x 151

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 781 are 11 x 71

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 694, 604, 620, 781

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(694, 604) = 209588

GCD(694, 604) = ( 694 x 604 ) / 209588

= 694 / 604

= 694

Step2:

LCM(2, 620) = 620

GCD(2, 620) = ( 2 x 620 ) / 620

= 2 / 620

= 2

Step3:

LCM(2, 781) = 1562

GCD(2, 781) = ( 2 x 781 ) / 1562

= 2 / 781

= 2

So, Greatest Common Divisor of 694, 604, 620, 781 is 1
